Chapter 6. Expressions and Operators

When more than one operator occurs at the same level of precedence, the BHT-BASIC
resolves the expression by proceeding from left to right.

a=4+5.0/20*2-1

In the above example, the operation order is as follows;

5.0/20 (=0.25)

0.25*2 (=0.5)

4+0.5

(=4.5)

4.5-1

(=3.5)
